5th Grade Force and Motion NC

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls a pencil to the ground when it falls.

Front

What happens to a moving object when a force is applied in the opposite direction?

Back

The object will slow down or stop because the opposing force reduces its speed.

Front

How does mass affect the motion of an object?

Back

An increase in mass makes it harder to accelerate the object, while a decrease in mass makes it easier to speed up.

Front

What is the role of gravity when an object is on a slope?

Back

Gravity pulls the object down the slope, causing it to accelerate.

Front

What is the effect of applying brakes on a bicycle?

Back

Applying brakes creates frictional forces on the wheels, which slows down the bicycle.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its state of motion, either speeding it up, slowing it down, or changing its direction.

Front

What is an example of an object that moves due to gravity?

Back

A pencil falling off a desk is an example of an object moving due to gravity.

Front

What is the effect of friction on a rolling ball?

Back

Friction slows down the rolling ball until it eventually comes to a stop.
